Which Batteries Are Best?

Our son researched which batteries gave you the best bang for your buck for his science fair project. A few of you wanted to see the results. Here they are!


Procedure
I purchased different kinds of batteries and connected them to a motor and timed how long they lasted.

Results
Some of the least expensive batteries had the best value.


Hypothesis
My Hypothesis was that the battery that cost the most would go the longest because companies make us think that if we pay more we will have a better product.

Suggestions
1. Buy batteries at the dollar store.
2. Buy batteries in large packs.
3. Buy batteries on sale.
